Obama jumbled his words as he welcomed guests to the White House to observe the Mexican holiday, sending the crowd into laughter before he referred to the day correctly.

"Welcome to Cinco de Cuatro—Cinco de Mayo at the White House," said Obama, in what appeared to be an attempt to note they were celebrating on the fourth of May instead of the fifth.

Cinco de cuatro means "five of four" in Spanish.

"We are a day early, but we always like to get a head start here at the Obama White House," he said.

During the presidential campaign, Obama acknowledged his Spanish skills weren't great.

"My accent's always been good," he said. "It's just that I only know 15 words."
